DHA (Docosahexaenoic acid), as an essential unsaturated fatty acid in the human body, has been extensively proven to play important roles in brain development, memory enhancement, and retinal formation. It is mainly derived from marine fish and algae. In some Nordic countries, it is a common practice to consider the heads of deep-sea fish as important food for children because they believe it contains an ingredient – DHA – that can make children smarter. The application of
Schizochytrium sp. powder (feed-grade DHA powder)
The encapsulated microalgae powder is mixed with an appropriate amount of antioxidant components such as vitamin E and selenium yeast. This mixture is then pre-mixed with conventional concentrated feed for lactating cows and further combined with the total mixed ration (TMR) using mixing equipment. Each cow consumes around 200-300 mg of pure DHA per day, resulting in levels in the milk that are 5-10 times higher than regular raw milk.
First, any well-equipped dairy farm can produce natural DHA raw milk. The production process involves the following aspects:
- Feed pre-mixing: Mixing the encapsulated microalgae powder with conventional concentrated feed using feed mixing equipment.
- Pre-feeding management: The introduction of a new raw material will inevitably affect the overall flavor and texture of the feed. Therefore, a pre-feeding period can be planned, typically lasting for one month and divided into four stages per week. During this period, the proportion of microalgae powder in the feed can be gradually increased, allowing the cows to adapt to the new raw material.
Next, monitoring the DHA content in the raw milk begins after two weeks of pre-feeding. Gas chromatography is used to analyze and test the DHA content in the raw milk. It is important to send the samples for testing as soon as possible after sampling and ensure uniform mixing of the samples during pre-processing. As the separation of milk fat is common in raw milk, it can cause significant fluctuations in the test data. To demonstrate the feeding effect, several batches of DHA testing can be conducted on the raw milk before feeding.
Finally, after the pre-feeding period, it enters the quantitative feeding stage, and the DHA content in the raw milk is monitored twice a month. It is important to pay special attention to sampling and testing the DHA content of the raw milk after adjusting the cow herd to observe any fluctuations.
raw milk are to establish a reasonable pre-feeding experimental plan before the pre-feeding period and strictly adhere to the formulation composition designed in the pre-feeding plan. This allows for a smooth and rapid transition into the constant feeding stage. During the pre-feeding period, the feeding management personnel need to pay special attention to the physiological performance of the cows during the feeding process after adding the new raw material to the feed formula. This includes monitoring their feed intake, mental state, and physicochemical data related to milk production. If any abnormal conditions occur, the feeding of the new raw material should be immediately stopped. In the constant feeding stage, it is necessary to regularly summarize the indicators of the raw milk and analyze the results.
HSF Biotech is a company that specializes in the research and development of nutritional products derived from Schizochytrium sp. The company has successfully developed a high-quality feed-grade DHA powder made from Schizochytrium sp. This powder is an excellent source of DHA, which is an important nutrient for animals' growth and development.
HSF Biotech uses advanced cultivation technology to ensure high-quality Schizochytrium sp. biomass production. The harvested biomass is then carefully processed to extract DHA-rich oil
